Answer:
Step-by-step explanation:
Probability (P) is calculated as
P = 
The first required outcome is a red sweet from a total of 3 + 5 = 8
P( red) = 
There are now 2 red left and a count of 7, since 1 has been eaten, thus
P( second red ) = 
P( red and red ) = × = 
=
Answer:
AB-C^2 = 3x^3 + x^2 + 9
Step-by-step explanation:
Hi
AB = (x^2)*(3x+2)= 3x^3 + 2x^2
C^2= (x-3)^2 = x^2 - 9
So
AB-C^2 = 3x^3 + 2x^2 - x^2 + 9 = 3x^3 + x^2 + 9

Answer: The mean of the data set is 25.
Step-by-step explanation:
To calculate the mean of a data set, first add up all the values.
17 + 34 + 19 + 27 + 30 + 23 = 150
Then divide the sum by the amount of values in the data set. Our sum here is 150 and the amount of data values is 6.
150 ÷ 6 = 25
